What about writing four subclasses of FilterOutputStream 
(NFCFilterOutputStream,
NFKCFilterOutputStream, NFDFilterOutputStream, NFDKFilterOutputStream)? Then
setUnicodeNormalization(true) can automagically wrap a NFCFilterOutputStream
around the output stream provided to the serializer.  Anyone wanting something
other than NFC can wrap the output stream by hand.
